Post-irradiation examination (PIE) is an indispensable step in the selection of new or improved research reactor fuel, and in the characterization and understanding of its in-core behaviour. This publication provides an introduction to PIE techniques. It describes a typical PIE process from intercycle inspections in the reactor pool or channel, to hot cell PIE, which is subdivided into non-destructive and destructive testing techniques with their typical output, advantages and drawbacks, and their applicability to understanding fuel irradiation behaviour. Much of the work presented in this publication originated from the research and development of new low enriched uranium research reactor fuels. Intended readers include research reactor operators, regulators and their technical support organizations, fuel developers and manufacturers, laboratory staff, and policy makers.

This guidebook gives a complete survey of destructive techniques available to perform microstructural examinations, elemental and isotopic analyses and measurement of physical, chemical and mechanical properties of irradiated fuel and structural materials, and describes asociated refabrication and instrumentation techniques. Non-destructive examination (NDE) data are verified by destructive examination (DE) data. The data were submitted to the IAEA by hot laboratories from 12 countries and one international organization (CEC/ITU) during the period 1992-1995. Together with IAEA Technical Reports Series No.322 (1991), Guidebook on non-destructive examination of water reactor fuel, it presents the most comprehensive summary of post-irradiation examination techniques to date.

There is high interest in new fuel types with increased accident tolerance. These range from using an oxidation resistant coating on zirconium based cladding to alternate fuel and cladding materials. These new fuels/claddings under development must be licensed before being deployed industrially and therefore research is being undertaken to assess their behaviour in various conditions. This publication arises from an IAEA coordinated research project (CRP) dealing with the acquisition of data through experiments on new fuel types and cladding materials and the development of modelling capacity to predict the behaviour of the components and the integral performance of accident tolerant fuel designs under normal and transient conditions. Demonstrations of improvements under severe accident conditions were documented. Several coated cladding materials were produced, tested, characterized and analysed in round robin tests carried out within the CRP. For improvement and validation of fuel performance codes, several benchmarks were organized to compare and analyse predictions of the extended codes. The findings and conclusions of the CRP are summarized in this publication.

Activation Analysis Handbook focuses on the importance of activation analysis in the examination of trace elements in materials. The book contains examples of activation analysis techniques and application of these techniques to provide solutions to problems in various scientific disciplines. Divided into four chapters, the book starts by giving an outline of the history and growth of activation analysis, including the general technique involved. The discussions proceed by taking into consideration the theoretical aspects of activation analysis, giving emphasis to basic concepts, sources of nuclear data and experimental methods, and selection of activation reactions. The book also considers the experimental methods in activation analysis. Other topics discussed are irradiation facilities; the preparation and encapsulation of samples; irradiations; and post-irradiation assays. The last part deals with the tabulation of elements and their corresponding atomic numbers; the key to tabulation; and a tabulation of nuclear data and experimental methods for activation analysis. The text is a good source of data for readers who are interested in activation analysis.
